i am wondering if it is possible to use 2 wireless routers at the same time. the main wireless router is hooked up to the cable modem and broadcasts wirelessly. about 150 feet from that i would like to add a wireless router that would share the internet connection. can 2 wireless routers talk to eachother in that way? example FLOOR 1 modem=>wireless router A=>PS3,NAS FLOOR 2 wireless router B=>PC,PC,notebook where the 2 pcs and the notebook are wireless and connect to wireless router B INSTEAD of wireless router A.
